Runtime Errors PXA_NO_FREE_SPACE

[Former Member]

Hi Team,

We are getting Runtime Errors "PXA_NO_FREE_SPACE" very frequently.

Current setting for parameter abap/buffersize is 300000 kB and for
abap/pxa is shared.

We have attached the ST22 log and Profile Parameters for SAP Buffers.

Suggest what value we can set for parameter abap/buffersize and abap/pxa.

Regards,
Prem Patel

Hi,

1.  Increase parameter  abap/buffersize

2.  Take restart of SAP system to affect changed parameter

Please set the abap/buffersize to 600000 KB

and leave the abap/pxa as shared.

600 MB of program buffer should be sufficient .

Hello,

There is no established rules.

I set the parameters based on experience and based on the systems usage.

Depending on the way the system is used the requirements may vary.

Som little sandbox systems work fine with the abap/buffersize set at 500Mb because there are few users connected. I had to set some others up to 1,2Gb.

One thing is, in general, the default parameters set by SAP right after the installation are not enough when the system is really used. I mean when yo have more than 20 users / developers working concurrently on your box.

I always double the initial abap memory buffers parameters provided as a starting point.

After that I modify the parameters based on the arising issues.

There are also some notes on SAP net that can guide you.

Regards,

Steve.

Hi Prem

1. Are you define the memory & buffer values based on Linux OS? refer the SAP Note

   941735 - SAP memory management system for 64-bit Linux systems

2.  Could you check this SAP Notes for runtime error

1773008 - SAPMSSY8 running too long

3. Your Kernel level are low, try to upgrade the latest one.

Hello,

Your ABAP/BUFFERSIZE is too small.

I usually set it to at least 750000 as a starting point.

Best regards.

Steve.
